PILE-WIRE NIECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 225,469, dated March 16, 1880.

Application filed November 18, 1878.

i To all whom it may concern Be it known that I, GEORGE DIXON, of Thompsonville, county of Hartford, and State of Connecticut, have invented new and useful Improvements in Pile-Wire Mechanism for Looms for Weaving Pile Fabrics, which improvements are fully set forth in the annexedv specification and in the accompanying drawings.

My invention relates to the devices employed on power-looms for weaving pile fab rics which operate to insert and withdraw the pile-wires from the fabric, and has for its objecta simplified and more economical and effective construction of suchdevices.

Referring to the drawings, which consist of four figures, Figure 1 is a side elevation, showing one side of the frame and carriagebed, cam and carriage actuating levers, and one side of the main carriage. Fig. 2 is a plan view of the bed, showing the latter and the carriage thereon. Fig. 3 is a view of the bed beneath the carriage in Fig. 2. Fig. 4 is a view of the main carriage, upon which is shown the wire-nipper carriage standing in the position in which it is when the nippers let go of the wire after pushing it between the warps.

In the drawings, A is the frame. B is a cariage-bed secured to the top of frame A. b is a carriage guide or rail on one edge of bed B. cis a groove in the upper face of bed B, running parallel to guide or rail b. i is an indentation in that portion of the face of bed B between groove c and guide or rail b. D is a channel cut in bed B from its edge opposite to guide or rail b, at right angles to groove c, of the same depth and width, and leading into the latter. 7L is the edge of the bed B opposite to guide or rail b, having the inclined form shown. n is a frog, pivoted on the face of bed B at o. i" is a spring connected to frog n and the under side of bed b. E is a driving-pulley on the end of a shaft, suitably adjusted to bearings in frame A, on the opposite end of which is secured a partially-grooved cam, on. t is a pin in lever P, and arranged to travel in the groove of cam m. lB is a lever pivoted to frame A at u. W is a connecting-bar pivoted at each end to levers P and R. Y is a con- P is a lever pivoted to frame A at sf necting-bar, pivoted to the upper end of lever R and to the main carriage H. H is a carriage arranged to move reciprocally on guide or rail b. 2 is the vertical, and 3 the h0rizoutal, side of carriage H. 00 a" are the channeled portions of the carriage, which lit upon guide or rail b. lF is a wire-nipper carriage arranged to move in or on carriage B reciprocally at right angles to the movements of the latter, having channels e e cut on each side thereof. 4t is a slot cut in side 3 of carriage H. 5 is a headed pin attached to carriage F, and projecting through side 2 of carriage H. 6 is a coiled spring-on pin 5. 7 is a fixed nipperjaw on carriage F. 8 is an oscillating nipperlever, likewise on carriage F, pivoted at z. c are wire and head grooves in nipper-jaw and lever 7 and 8. 9 is a spiral spring attached to carriage F and to Dipper-lever 8. l0 is a lever pivoted on the side of carriage F, one end bearing on top of nipper-lever 8 and the other extending out over face 3 of carriage H. 1l is a vertically-moving pin inserted down through carriage H, its lower end resting on bed A between groove c and guide or rail b, and its opposite end projecting up above the surface of face 3 of said carriage under the long arm of lever 10. l2 is a part of a pile-wire,

frame and bed of the machine provides for y causing the carriage H, when pulley E is revolved, to move reciprocally on bed B, and when my devices are located in proper position, with the wide end of said bed near the side of the carpet-loom, said carriage will be moved to and from the edge of the fabric as it passes through the loom, and carriage F rides on carriage H, remaining stationary thereon during the movement of the latter from the loom, but moving across it as it approaches the loom, caused to do so by the action of the inclined edge la of the bed upon stud 13 fixed upon the bottom of carriage F. As saidcarriage moves across carriage H it IOO acts against the spring 6, which, when carriage H has returned to its position near the loom, causes carriage F to move in the line of channel D back to the position it was in when carriage H began its movement from the loom. The position of the parts, as seen in Fig. l, shows them justv previous to the movement of carriage H from the edge of the Jfabric in which the pile-wires are being employed, with the headed end of one of the wires between the nipping-jaws 7 and 8.

When carriage H begins to move from the loom the lower end of pin 1l strikes the beveled edge of indentation in bed B, and is thereby driven upward, striking the under side of one end of lever l0, causing its opposite end to bear down upon the rear end of lever 8, thus causing the head of wire 12 to be grasped between jaws 7 and 8, and as the carriages move back said wire is drawn out from the woven fabric.

The reverse or forward `movement of both carriages has alreadyr been described, together with the consequent lateral movement of carria-ge F. When the wire is drawn out it is caught up near its forward free end by a swing-- ing hook of ordinary construction, and by it said free end is carried back into a position opposite the shed oi the warps, so that as the carriages advance, pushing the wire, the latter will be inserted in its proper place in the fabric. When the carriages have advanced'far enough to so insert the wire, pin 11 drops into indentation fi, operating by the heretofore described devices to open jaws 7 and 8, leaving the head ofthe wire free, and spring 6 draws the carriage F again to a position to repeat the aforesaid operation, and to bring the nipping-jaws again into position to withdraw an? other wire.

What I claim as my invention isl. The bed B, provided with guide or rail b, and having indentation t', carriage H, adapted to engage and slide upon said guide I), and provided with pin 11, in combination with carriage F, provided with the wire-nipping jaws 7 and 8, lever 10, spring 9, and mechanism for reciprocating said carriages, substantially as and for the purpose set forth.

2.1The bed B, provided with groove c and channel D, at right angles to each other, and having the inclined edge h and frog n, vin combination with carriages F and'H and mechanism to reciprocate the same, pin 5, and spring 6, substantially as and for the purpose set forth.
